TO ALL WI-IOM IT MAY CONCERN:

Bc it knownthat I, JESSE CONVER, of the city and county of Philadelphia, State of Pennsylvania, have invented a new and vuseful Improvement in Heat-Radiators and Dampers Combined; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, making apart of this specification, and which shows a perspective view of my apparatus.

My invention consists in an improvement on heat-radiators, mainly composed of parallel circular plates, to which I add a cylinder and a damper, so combined with the plates that, without destroying the heat-radiating effect of the apparatus, I render it more eifective by being able to moderate or increase the radiation at will.

To enable others skilled in the art to make and' use my invention, I will now proceed to describe its construction and operation. 1

S S is a sectionof the body of the -stove into 'which my apparatus is placed.

The apparatus, as shown in the drawings, is. composed of a cylinder, c c c, on which are set circular convei plates A A A and B B B. The first, third, and fifth plates are of the same diameter as the inside of the stove, while the second, fourth, and sixth are of a smaller` diameter. The bottom plate B is made in the shape of a cone, as shown by dotted lines y m. The vertex ofthe cone is placed inside the bottom of cylinder e, but so as to allow a spacebetween the cones surface andthe interior of the cylinder; circular holes H H have been made in cylinder c c between the first and second plates, and also between the fourth and fth ones. A damper, of `which D D is the handle, has been placed immediately below top holes H H. Said damper is constructed in the ordinary way, viz, composed of handle D, and a metallic disk held in proper place inside cylinder c c'.

My apparatus thus completed is placed in thc stove so ,as to have the' cone B standing above the replaee, as most radiators of a similar construction are. The ire being made and lighted, and damper D being kept wide open, the smoke andhcat will come up, strike against cone B, then force itself up between cone B and plate A, which, being of the same diameter as the stove, will oblige the smoke and heat to g'o up cylinder e, and thence to the smoke pipe, thus affording a goed strong draught of air to start the fire with. New, as soon as the ire is fairly started, 'if I shut damper D tight, the heatwill have to come out through holes H H, going up around plate B; thence through holes K and K', made in plate A; thence around plate B, and up the smoke pipe, through holes H- I'I, situated, as has been said, above damper D. K

I am fully aware'that dampers and heat-radiators mainly composed of radiating plates,ot` a construction nearly similar to the apparatus hereinabove described, have been'already invented, patented, and used; and I do not intend claiming broadly my apparatus; but what I do claim as my invention, and desircr'to secure by Letters Patent of theUnited States, is

Cylinder ce, damper D, holes H H and H H and I( K, constructed and combined with plates A. A, B B, A A', B B', A A, and cone-plate B B", lin the manner andfor the purpose above set forth and described.
